It’s one of the major causes of death in the U.S. A heart attack
(also known as myocardial infarction) occurs when blood flow to a
section of heart muscle becomes blocked, preventing it from receiving
the oxygen it needs. Unless it’s treated quickly, the muscle may become
damaged and die.

Heart Attack Symptoms

The signs and symptoms of heart attacks can vary from person to person. They include:

Pressure, fullness, or a squeezing discomfort in the center of the
chest. This discomfort may reach to the shoulders, arms, jaw, and back,
and can last for more than a few minutes. (Angina, which has similar
symptoms, goes away with rest.)

Shortness of breath

Sweating

Lightheadedness, weakness, possibly even fainting

Nausea and vomiting

Impending sense of doom

When in Doubt, Call 911.

A heart attack is a serious and often fatal condition. If you think
you or someone with you is experiencing a heart attack, you should seek
medical attention immediately by dialing 911. If the blood flow can be
restored in time, damage to the heart can be limited or prevented
